The La Liga champions are quoted as having told the BBC that talks with the Gunners yesterday became “official”.
“An informal conversation with Arsenal became formal on 1 June and now an official approach has been made to the club,” a Barcelona spokesman told the BBC.
“Everyone knows that Cesc wants to play with Barca and everyone know we want him to sign but here there is a third actor that is Arsenal,” Barcelona director general Joan Oliver told the club’s official website.
“Yesterday [Tuesday] we presented a concrete offer and have written to Arsenal,” he added.
FÃƒÂ bregas, 23, moved to Arsenal from Barcelona aged 16 and became captain at Emirates Stadium in 2008. The Spaniard has scored 46 goals for the north London side.
The Spain midfielder last week spoke of his respect for ArsÃƒÂ¨ne Wenger after he told the Arsenal manager he wanted to leave north London this summer.
“I respect him so much,” said FÃƒÂ bregas. “He told me to concentrate on my football and the World Cup and he will deal with whatever happens in my future.
“It was probably the greatest conversation I have had with someone in my life.”
FÃƒÂ bregas played alongside some of Barcelona’s current top stars, including Lionel Messi, before his move to Arsenal seven years ago.
